Description
Technical field
The utility model belongs to escalator checking measurements instrument, particularly a kind of escalator hypervelocity, non-operating reversed tester.
Background technology
Constantly perfect along with urban construction, escalator has become the indispensable part in market, Metroplises, and its safety is by extensive concern.And escalator brake is safety device that is most important, most critical, its safe, the reliable safe operation directly affecting staircase.Therefore whether staircase drg meets standard, code requirement seems most important, existing test hypervelocity, deficient speed, non-operating reversed defencive function method mainly adopt proximity switch, travel switch, photo-electric speed monitoring method of testing, in use there is following problem: 1, take off data can not be preserved, display data volume is few, not directly perceived, inconvenient operation; 2, measurement process is complicated, and degree of automation is low, needs the manual control beginning and ending time; 3, the work of data subsequent treatment cannot be carried out, and cannot meet the requirement of informationization, Automatic data processing.
Summary of the invention
The purpose of this utility model is exactly the problem solving existing escalator hypervelocity, deficient speed, the test of non-operating reversed defencive function; a kind of escalator hypervelocity, non-operating reversed tester are proposed; can fast and actv. test; and to Measurement and Data Processing, analysis, storage, can greatly increase work efficiency and accuracy of measurement.
The purpose of this utility model is achieved in that a kind of escalator exceeds the speed limit, non-operating reversed tester, comprise signal analyzer, the power input of signal analyzer is connected in parallel mains-supplied module and UPS back-up source, the signal input output end of signal analyzer respectively connected the speed encoder of tested staircase, proximity switch and phase detector, speed encoder, the signal input part of proximity switch and phase detector is connected with a fault signal generator respectively, signal analyzer is connected with the emergency stop switch of tested staircase by time fine motion master cock, this signal analyzer also respectively connected LCDs, upper computer interface, memory cell and keyboard.
Domestic and international current existing test escalator hypervelocity, non-operating reversed instrumentation, conventional test methodologies adopts proximity switch, travel switch, photo-electric speed monitoring method of testing, and operated in accordance with conventional methods is complicated, and accuracy of measurement is poor.The utility model adopts liquid crystal display, and display is more directly perceived, and automatically tests the braking beginning and ending time by signal transducer, makes take off data more accurate.The utility model adds memory cell, can preserve, enquiry of historical data is connected with PC and carries out data analysis to take off data.The utility model fully demonstrates intelligent feature in data processing, realizes easy to operate, and take off data is special measurement instrument accurately.
The utility model improves conventional test methodologies, achieve existing special test equipment to improve in the display of test data, the process of data and analysis, the browsing of data, preservation etc., increase signal transducer simultaneously, realize intellectuality and the accuracy of measurement of this instrument.The utility model product design structure is simple, and overlap power subsystem unit with civil power and standby UPS two, stable and reliable for performance, intelligence degree is high, commonality good, can greatly increase work efficiency and measure precision.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is connection structure block diagram of the present utility model.
Detailed description of the invention
A kind of escalator hypervelocity, non-operating reversed tester, as shown in Figure 1, comprise signal analyzer, the power input of signal analyzer is connected in parallel mains-supplied module and UPS back-up source, adopt two cover power modules to carry out the functional reliability that power supply can improve utility model greatly, prevent loss of data.The signal input output end of signal analyzer respectively connected the speed encoder of tested staircase, proximity switch and phase detector, the signal input part of speed encoder, proximity switch and phase detector is connected with a fault signal generator respectively, signal analyzer is connected with the emergency stop switch of tested staircase by time fine motion master cock, and this signal analyzer also respectively connected LCDs, upper computer interface, memory cell and keyboard.Faulty generators modulating output is utilized to run hypervelocity, owe the abnormal work signals such as speed and non-handling reverse in escalator detection process, monitor staircase control monitor unit can identify and provide control response signal simultaneously, whether inspection can reliably cut off electrical safety loop, staircase service brake mechanical action band-type brake (additional brake band-type brake action simultaneously), makes staircase out of service.This signal analyzer also distinguishes connecting fluid crystal display screen, storage element, upper computer interface and keyboard.Said memory cell is RAM (random access memory) card read-write memory cell.
LCDs can show multirow data, can show simultaneously and record simulation hypervelocity speed, reverse test data, unit after the phase place of signal, mode of operation, measuring equipment numbering, pendulous frequency, calculating, display information more greatly, more intuitively.
Time controling micro-switch is connected with the emergency stop switch of staircase, and after signal conversion processes, enter signal processing unit be connected with signal analyzer central process unit input end, test operation is more convenient, take off data is more accurate.
Upper computer interface can facilitate the utility model to be connected with PC, carries out follow-up data analysis.
